Abstract

We summarize the enabling technologies for broadband millimeter-wave communication at W-band. These enabling technologies include photonics-aided broadband signal generation, high-spectral efficiency modulation format, multiple-input multiple-output (MIMO) reception, high gain antenna, optical and electrical multi-carrier modulation, antenna polarization multiplexing and multi-band multiplexing, advanced digital signal processing (DSP), and heterodyne detection. Based on these advanced technologies, we have realized over 400G wireless signal transmission and over 2.5-km wireless delivery with a bit rate up to 50Gb/s at W-band.
